3. A corn-planter comprising a wheeled platform mounted upon said frame, hoppers provided with chutes arranged upon said platform, a fixed perforated plate mounted in the chute of each hopper, oscillating plates carried by said fixed plates, said oscillating plates being provided with perforationsarranged for registration at times with the perforations in the said fixed plates, lugs carried by said oscillating plates,

aft carried by said platform, trip members each of its ends, said trip member being arranged for engagement lugs, an arm carried by said rock-shaft and extending upwardly thereom, a vertical shaft mounted upon one of said hoppers, means for rotating said shaft,

arms carried by the upper end of said shaft and extending in opposite directions therea rockfrom, the said arm on the said rock-shaft benormal position. In a corn-planter the combination with a wheeled frame of a platform carried thereranged to register at times with the perforations in the said fixed plate, lugs carried by said oscillating plate, upon said platform, trip members carried by said rock-shaft at each of its ends and arranged for engagement with the said lugs, an arm carried by said rock-shaft, means carried by one of said hoppers for engagement with said arm whereby the said shaft is rocked, and a spring connected to said trip member and the said chute for returningthe said rock-shaft to its normal position,
